I have a 93' Lexus LS400 with 109k miles and the gas, speedometer, and tacometer gauges are lit up fine but only work intermitently. The gas gauge never goes above half full, but is usually on empty, even when there is plenty of gas. Also, you can tell what time the digital clock reads, but it has dark parts on the display like something is wrong. Now, I was wondering if this could be linked to my car running like the exhaust is clogged at low speeds and me having to take my foot off the gas and put it back on to power through it and it sounds like it is misfiring and just drives horribly, but I can get it up to highway speeds where it runs much better and gets decent gas mileage. I had a full tune-up, had the cats checked, and had a compression test done on the engine and nobody can find the problem Could there be fuses burnt out that affect the computer and make my car run horribly and also prevent the instrument cluster from working properly even though it is lit up perfectly?
You have two separate problems. The instrument cluster for
the old ls 400s are known for failing or partially working. Bad
news is that replacing it is the only way to get your instrument
cluster back. The price for this is more than one thousand dollars. For your other problem, it sounds that your EGR system is failing or you have a vacuum leak. If you instrument cluster is not working you probably cant see the check engine light illuminated. The only way to retrieve codes to help a technician diagnose it is by reading how many times the check engine light blinks. Take your vehicle to a Lexus dealership and get it done right.
